How long does a McDonald's cheeseburger last?

Answer 1

"Color of Beef

Beef muscle meat not exposed to oxygen (in vacuum packaging, for example) is a burgundy or purplish color. After exposure to the air for 15 minutes or so, the myoglobin receives oxygen and the meat turns bright, cherry red.

After beef has been refrigerated about 5 days, it may turn brown due to chemical changes in the myoglobin. Beef that has turned brown during extended storage may be spoiled, have an off-odor, and be tacky to the touch."

Answer 2

Foods that are left out in room temperature for more than an hour can begin bacteria growth. Our stomach acids can kill some of these bacterias but not all and some can make you very sick. Keep foods OUT of the danger zone- Above 45 degrees and Below 145 degrees. Between these temperatures bacteria lives and breeds on our foods.
